Thermador Oven not self-cleaning
When your Thermador oven self-clean cycle is not working, the touchpad is the most likely cause, especially if the door lock indicator does not light and you do not hear the door lock motor running when you press Self-Clean. A faulty touchpad may need replacement. If the cycle starts but the Thermador oven door will not unlock afterward, check the door lock motor and switch assembly. The temperature control thermostat is another possibility because it regulates voltage and temperature during self-cleaning, even if the oven works normally for baking and broiling. A damaged door latch or faulty latch microswitch can also prevent the cycle from starting because the door must lock for safety. Less commonly, a defective oven control board or main control board may fail to send voltage to the bake and broil circuits. Inspect the latch and wiring, and use a multimeter only if you are comfortable testing continuity and live-circuit components. Enter your Thermador oven model number to find the exact replacement touchpad, door lock assembly, thermostat, latch, or control board for your appliance.
01 - Thermador Range/Stove/Oven Touchpad
The door lock indicator light should come on and you should hear the lock motor running when the self-clean button is pressed. If the indicator light does not come on and you don't hear a low humming noise as the door is being locked, it's likely the oven's touchpad is faulty and will need to be replaced.

02 - Thermador Range/Stove/Oven Door Lock Motor and Switch Assembly
During the oven's self-cleaning cycle, the door lock switch activates the door lock motor to prevent the oven door from being opened. If the door lock motor and switch assembly is defective, the oven door will not unlock once the self-cleaning cycle is complete. On most ovens, you can open the oven door by removing certain screws or panels. Check your owner's manual for further instructions.

03 - Thermador Range/Stove/Oven Temperature Control Thermostat
The oven thermostat sends voltage to the heating circuit and regulates the temperature of the oven during the self-cleaning cycle. It is possible for the oven thermostat to function properly for baking and broiling but not for cleaning. Due to its complexity, the oven thermostat is difficult to test. If you suspect the oven thermostat is at fault, replace it.
Highly Likely
04 - Thermador Range/Stove/Oven Door Latch
For your safety, the self-clean cycle will not begin unless the oven door is locked. If the door latch is broken and unable to allow the door to be locked, the self-clean cycle will not begin. Inspect the latch for damage. You can also use a multimeter to test the latch assembly's microswitch, if applicable, to determine if the switch has appropriate electrical continuity. If the latch is damaged or the microswitch tests negative for continuity, the door latch should be replaced.
Highly Likely
05 - Thermador Range/Stove/Oven Oven Control Board
The oven control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
Highly Likely
06 - Thermador Range/Stove/Oven Control Board
The control board has relays that send voltage to the bake and broil circuits according to the user settings and sensor input. If the control board is defective, it may not send voltage to the heating components.
